OPERATIONS MANAGEMENT DEME 2.3 6th Sem May 2k5

Max Marks 60

Note: Section A is compulsory. Attempt any Four questions from Section B and any Two questions from Section C.

Section A Marks 2 each
1.
(a) Define operations management and name the three approaches of management.
(b) What is meant by Product Design and Development?
(c) Draw and label a product life cycle.
(d) What do you understand by Capacity and man Power Requirement Planning?
(e) What is the effect f location changes on the cost of a product?
(f) Give the objectives and functions of materials management.
(g) What are the steps in designing a management information system?
(h) Differentiate between forecasting and prediction.
(i) Discuss in brief preventive maintenance.
(j) Differentiate between lead time and Reorder point.

Section B Marks 5 each

2. Discuss the role of a customer in improving the quality of a product.

3. Discuss the various production control functions.

4. A hospital has experienced irregular and usually increasing, demand for disposable kits throughout the hospital. The demand for a plastic disposable tubing in pediatrics for January was 300 units and for February 350 units. The old forecast procedure was to use last year’s average monthly demand of the forecast for each month this year. Last year’s average monthly demand was 200 units. Using 200 units as the January forecast and a smoothing coefficient of 0.7 to weight recent demand most heavily, calculate the forecast for the month of February and March.

5. Derive a relationship to calculate Economic Order Quantity where C = Total cost per year, Q = Lot size, H = annual holding cost, D = Annual demand and S = Ordering cost.
Plot a graph to show the same.

6. Discuss the application of concurrent Engineering in Product Design and Development.

Section C Marks 10 each

7. Discuss the salient features of three major philosophies and their impact on quality.

8. Name the process which eliminates 100^ inspection. Discuss the seven Basic Tools of Statistical Quality Control with examples.

9. (a) What s process capability? Show it graphically.
(b) Discuss the concept of Six sigma with example.

Max Marks 60

Note: Section A is compulsory. Attempt any Four questions from Section B and any Two questions from Section C.

Section A Marks 2 each
1.
(a) Identify different types of productivity.
(b) What are ergonomic considerations in product design?
(c) Identify different techniques of forecasting.
(d) Distinguish between MRP-I and MRP-II
(e) Identify need for capacity planning.
(f) Define lead time and reorder point.
(g) Identify requirements of effective MIS.
(h) State the benefits of control charts.
(i) Identify benefits of planned maintenance.
(j) Identify elements of planned maintenance.

Section B Marks 5 each

2. Describe briefly the characteristics of various types of production systems.

3. Identify and briefly discuss the steps involved in product design and development.

4. Explain exponential smoothing technique. Discuss the choice of smoothing coefficient. A company uses exponential smoothing with ? = 0.1 to forecast demand. The forecast for the month of February was 500 units whereas actual demand turned out to be 450 units. Forecast the demand for the month of March.

5. Derive an expression for EOQ. The annual demand for an item is 3600 units. The cost of placing an order is Rs. 16 and cost of holding inventory is 25% of investment in inventories. The price per unit is Rs. 8. Determine EOQ.

6. Explain the forms AQL, LTPD producer risk and consumer risk for a sampling plan. Distinguish between control charts for variables and control charts for attributes.

Section c Marks 10 each

7. (a) Identify the reasons for increased use of computer based information systems. State the salient features f computer based MIS.

(b)Identify the operating elements of MIS. Describe briefly the processing fuctions of information systems.

8. (a) Describe briefly the basic model of a control system for planned maintenance with the help of a neat sketch.

(b) Identify and briefly discuss various techniques of condition monitoring.

9. Write notes on any two f the following:
(a) Concurrent Engineering
(b) Aggregate Planning
(c) Operations Scheduling
(d) Total Predictive Maintenance.
